Abstract
(A1) Die Erfindung betrifft ein Verfahren zum hochfesten Kleben von Bauteilen aus gleichen oder unterschiedlichen Werkstoffen. Sie ist ueberall dort einsetzbar, wo derartige Bauteile mittels der Fuegetechnik Kleben verbunden werden. Insbesondere ist die Erfindung vorteilhaft im Automobil-, Flugzeug- und Maschinenbau sowie dazu verwandten Industrien einsetzbar. Das Verfahren zum hochfesten Kleben von Bauteilen aus gleichen oder unterschiedlichen Werkstoffen ist erfindungsgemaess dadurch gekennzeichnet, dass die Klebeflaechen fuer den eigentlichen Klebvorgang mit dem jeweils zum Einsatz kommenden Klebstoff beschichtet werden und davor oder danach durch die beiden Klebflaechen der jeweils zu fuegenden Bauteile eingebracht werden und dass diese Loecher, Fugen und/oder Schlitze mit einem Klebstoff oder niedrig schmelzendem Metall ausgefuellt und gehaertet werden. Bei dickeren Klebfugen koennen auch zunaechst in beide Fuegeteile Loecher, Fugen und/oder Schlitze eingebracht werden. Beim Fuegen der mit Klebstoff beschichteten Bauteile dringt der Klebstoff dann auch in die Loecher, Fugen und/oder Schlitze.
DE 102007010540 A1 UPAB: 20081110 NOVELTY - The method for adhering components from same or different metals useful in the automotive-, aircraft- and engineering- and related industries, comprises coating adhesive surfaces of the components to be joined with an adhesive for actual adhesion process, introducing conical holes, joints and/or slots in the adhesion surfaces by a neodymium-doped yttrium aluminum garnet laser after coating, filling the holes, joints and/or slots with fast-hardening adhesives and then hardening. The holes, joints and/or slots are permeable and are diagonally introduced to the surface. DETAILED DESCRIPTION - The method for adhering components from same or different metals in the automotive-, aircraft- and engineering- and related industries, comprises coating adhesive surfaces of the components to be joined with an adhesive for actual adhesion process, introducing conical holes, joints and/or slots in the adhesion surfaces by a neodymium-doped yttrium aluminum garnet laser after coating, filling the holes, joints and/or slots with fast-hardening adhesives and then hardening. The holes, joints and/or slots are permeable, are diagonally introduced to the surface during tensile stress of the adhered components, and have changing directions. Contour sections act as the holes, joints and/or slots, where slots are S-shaped with oblique sections. Oblique boring and oblique cutting edge are implemented for the production of holes, joints and/or slots after trepanning process. Cyanacrylate and/or low-viscous 2-K-epoxide resin and/or ultraviolet activated- or ultraviolet hard adhesive system are used as fast hardening adhesives. The holes, joints and/or slots are introduced into the join parts and then the adhesion surfaces are coated with the adhesive that penetrates into the join parts. The adhesive is temporarily heated and then flows into the holes, joints and/or slots. The temperature lies under the hardening temperature. Hot-melts are used as adhesive, are heated up to melting and flow into the holes. The heating and cooling of the adhesive in the holes, joints and/or slots take place before hardening the adhesive surfaces. The low-melting metals are introduced into the holes, joints and/or slots. The hardening of the adhesive surfaces is integrated into a continuous overall process. The hardening of the adhesive surfaces takes place in the cathodic immersion lacquer process during the application in the automobile industry. The already hardened adhesive is displaced with specified adhered rivet. The strengthening takes place by filling materials. The adhesives are strengthened in the holes, joints and slots to increase their firmness. The fiber strengthening of the adhesive takes place by carbon fibers, glass fibers and or textile fibers. Carbon-nanotubes and/or particles in micro- or nano-size are used as the filling materials. USE - Method for adhering components from same or different metals useful in the automotive-, aircraft- and engineering- and related industries. ADVANTAGE - The method ensures effective and economical adhering of components with high-strength and provides high-stability to the adhered places and areas.
